Hello guys,
I took this photo some time ago, and i really forget how i get these purple tones. I edited this photo in photoshop. I tried now on a similar photo (because i lost the raw of this) to make these purple tones with curves, gradient map but i cant took similar result.
If someone can help me, i will be grateful

Perhaps try increasing the magenta slider in the saturation tab.

Will not work because, where you see purple now, was a grey before

In PS try a hue saturation layer, and a mask to keep the tint off the areas you don't want. Or possibly a photo filter of the color you want, then use the opacity slider to adjust the effect. In masks rather than selecting individual objects, you can also use color range (mask properties box) to select individual colors or clusters of colors to mask). Use the fuzziness slider to smooth the edges of the masks.
